Winding, grinding noise behind dashboard

[Sonei]

Hi.
I have a winding, grinding noise behind the dashboard in the steering wheel area. The noise starts approximately after 15 minutes of driving. The other day, after laying on my horn, the noise started up. Maybe a steering damper issue?
I feel as though aggressively moving the steering wheel left and right while driving affects the noise. The noise ceases when at a full stop.
I do have a service appointment in a few weeks but figured I would throw this info out there for some possible insight.

Hi Sonei, I think others have posted that this is either a worn/defective bearing in the steering unit or perhaps the electric steering unit is defective. DaBull

Thank you DaBull.

What is "the electric steering unit" ?

Isn't steering supported hydraulically?

The power steering fluid would tend to support that theory
One cause of grinding noise is a bad SW centre bearing. I believe a few of these have required replacement.

Hi emax, I think the steering unit is powered by electric vs belt driven and the electric motor powers a hydraulic fluid pump. Not an expert. Anyone else want to weigh in.

That's correct. It's an electric motor operating a remote mounted pump. It's the source of the whistling sound that some owners have reported. Load up the steering with the engine operating and the vehicle stationary and you can hear the pump operating.

On my RHD vehicle the pump and motor are located above the left side frame rail just behind the left headlight. Visible in this pic taken from below (green decal is on the motor housing). Left of this pic is front of the vehicle.

Sorry. I don't log in much. It was a loose gearbox cable due to a faulty clip that had to be ordered.

If it was like my noise, (a chinkling sort of noise) , if you have a snorkel it could be the wind flowing past the top 5"or so. Our mechanic found the cause in my car. Push some foam into gap and see what happens. It fixed mine. I improved my foam placement to a more permanent fitting.

Reckon it's the steering servo, either that or you have my mother inlaw stowing away in the engine bay.
